RUNNER FOR BOB-SLEIDS.

SPECIFICATION forming part of Letters Patent No. 402,954, dated May 7,1889.

Application filed January 19, 1889. Serial No. 296,390. (No model.)

To all whom it may concern:

Be it known thatI, TARGE G. MANDT, a citizen of the United States, and aresident of Stoughton, in the county of Dane and State of Wisconsin,have invented certain new and useful Improvements in Runners for Bob-Sleds; and I do hereby declare that the following is a full, clear, andexact description of the invention, which will enable others skilled inthe art to which it appertains to make and use the same, reference beinghad to the accompanying drawings, which form a part of thisspecification.

This invention relates to runners for bobsleds.

The object is to produce a runner for bobsleds provided with means forholding the rave and cross-beam in place thereon; furthermore, toproduce a runner which shall be simple of construction, efficient anddurable in use, and comparatively inexpensive of production.

With these objects in view the invention consists in the combination,with the knee of the runner of a bob-sled, of standards secured theretoextending above the cross-beam and to which the rave is secured, wherebythe cross-beam will be free from the rave, and thus allow the runner ofthe sleigh to oscillate; furthermore, in the combinatiomwith the runnerprovided with standards extending above the bearing of the cross-beam towhich the rave is attached, so as to allow the beam to be free from therave in order to allow the runner to oscillate, of a flange formed inthe end of the runner and forming abearing to which the end of the raveis secured, whereby the runner will be additionally strengthened; and,finally, in the various novel details of construction, as will behereinafter fully described in the specification, illustrated in thedrawings, and pointed out in the claims.

In the accompanying drawings, forming part of this specification, and inwhich like letters of reference indicate corresponding parts, I haveillustrated one form of device embodying the essential features of myinvention, although the same may be carried into effect in other wayswithout in the least departing from the same.

In the drawings, Figure 1 is a perspective view of the runner, showingthe rave secured to the brackets on the knee and the crossbeam in place.Fig. 2 is a perspective view of the runner with the rave and cross-beamremoved. Fig. 3 is a top plan view of the runner, and Fig. 4 is adetailview of the crossbeam.

Referring to the drawings, A designates the runner; B, the knee, whichmay be either secured to or made integral with the runner; O, the rave,resting upon standards D, formed on the top of the knee; and E,the cross-beam upon which the sleigh-body is secured.

In carrying this invention into effect the runner A, knee B, andstandards D may be made of one piece-- that is, of cast metal; but,ifdesired, as before stated, they may be secured upon the runner in anysuitable manner. Upon each side of the knee are formed the standards D,upon which the rave is secured. These standards are provided on eachside with ears cl, formed with a recess, 61', through which extend bolts61 for holding the rave in place thereon. The end of the runner isprovided on one or both sides with a flange, a, provided with openingsa, through which bolts extend to hold the rave securely in place.

As shown in the drawings, only one flange is used, and the outer side ofthe end of the runner is formed into an ear, a provided with arecess,athrough which extends a bolt, a, which passes up throughthe end of therave, thereby additionally securing it. The space between the twostandards D forms a recess, in which fits the beam E, and the brace 12,which forms the top of the knee proper, is provided with a. semicircularridge, b, forminga bearing on which the end of the beam E rests, and byreason of its shape allows the said beam to oscillate, so as to presenta smoothriding runner, and one which will adapt itself to any inequalityor roughness in the road. Directly below the semicircular ridge isformed a groove, 6 designed to form a bearing for a U-shaped bolt whichpasses through the end of the cross-beam and fits in the said groove. Aswill be observed, the rave is entirely free from the cross-beam, so thatit will be allowed to oscillate without coming in contact with the saidrave.

I am aware that the idea of having a rave upon a sleigh is not new; butthe idea of providing the knee with standards to which to secure therave, so as to keep it outof contact with the cross-beam, and the ideaof securing the beam movably below the rave are new.

It will thus be seen that by constructing a sleigh-runner with standardson the knee, so

as to admit of the rave being rigidly secured above the cross-beam andto the end of the runner, and by reason of the movable cross-beam aneasy-riding bob-sleigh will be produced.

Having thus fully described my invention,

what I claim as new, and desire to secure by Letters Patent, is-- 1. Arunner for sleds having a knee formed integral therewith, provided witha curved bearing'for the cross-bea1n, and standards rising from. saidknee provided. with support TARGE G. MANDT.
